CC-KREB05 Honeywell C300 Redundancy Manager Firewall

Product Description

The CC-KREB05 is a high-integrity Control Firewall and Redundancy Module engineered for the Honeywell Experion PKS C300 controller environment. This module provides a dual-purpose solution: it serves as a specialized industrial firewall to protect the C300 controller from unauthorized network traffic while simultaneously managing the synchronization and seamless failover between primary and backup controllers. By isolating the critical process control network from external Ethernet or TCP/IP interference, the CC-KREB05 ensures deterministic communication integrity and cybersecurity resilience.

Designed for continuous, mission-critical operations, the CC-KREB05 incorporates advanced traffic filtering and hardware-level fault detection. It facilitates rapid controller switchover with zero impact on process logic, making it an essential component for fault-tolerant automation architectures. We supply this module as 100% brand new and original equipment, fully compatible with standard Honeywell C300 series racks.

Engineering Advantages

• Cybersecurity Hardening: The CC-KREB05 creates a secure perimeter around the C300 CPU, mitigating risks of broadcast storms or unauthorized access that could compromise plant safety.

• Deterministic Failover: The module manages high-speed data mirroring between redundant pairs, ensuring that the backup controller is always "hot" and ready to assume control in milliseconds.

• Reliable Diagnostics: Integrated event logging allows maintenance engineers to perform root-cause analysis on network anomalies or redundancy triggers directly through the Experion PKS console.

FAQ

• Is the CC-KREB05 required for every C300 controller?While a C300 can operate without it, the CC-KREB05 is highly recommended for any system connected to a broader plant network to ensure both cybersecurity and redundancy synchronization.

• Does this module support Fault Tolerant Ethernet (FTE)?Yes, the CC-KREB05 is specifically designed to interface with Honeywell's FTE architecture, providing the necessary isolation and routing for redundant network paths.

• What is the difference between CC-KREB05 and standard network firewalls?Unlike IT firewalls, the CC-KREB05 is purpose-built for the C300 backplane. It understands proprietary control protocols and ensures that safety-critical data packets are never delayed by filtering processes.
